visit knoppix.com and download their Knoppix ISO, they have a packet
monitoring utility... etherReal, which is a very effective,
configurable "FREE" network sniffer.  And if your network is
segmented, because it's a LIVE CD (meaning you don't have to install
it to use it, you just boot from it) you can take the CD anywhere and
save the results down to a thumbstick or floppy.


good luck
